toothless rat
2012-08-23 21:19:53

Lee Rannals for redOrbit.com — Your Universe Online Imagine a rodent that doesn't come out of a U-shaped hole in your wall to eat cheese, simply because it is unable to craft such a home. Well, a new species of rat lives up to that thought. A species of near-toothless rat was found in Indonesia, living off earthworms and spending its time sucking and slurping instead of chewing or gnawing. The animal, paucidentomys vermidax, is the only rodent scientists have found out of the...

Fossilized Teeth Point To World’s Oldest Grasslands In Chilean Andes
2012-07-25 05:14:14

Brett Smith for redOrbit.com - Your Universe Online Two newly discovered and ancient rodent species, including the earliest known chinchilla, may have lived in the world´s oldest grasslands about 32.5 million years ago. The discovery and subsequent analysis of the teeth by an international team of researchers, which was published in the journal American Museum Novitates, supports previously collected evidence indicating that these animals once inhabited an open and dry environment...

Rodents Do Their Part To Help Save Tropical Trees
2012-07-17 06:07:04

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online There's no honor among thieves when it comes to rodent robbers – which turns out to be a good thing for tropical trees that depend on animals to spread their seeds, according to recent research. Big seeds produced by many tropical trees were probably once ingested and then defecated whole by huge mammals called gomphotheres that dispersed the seeds over large distances. But gomphotheres were...

Could The Naked Mole Rat Hold The Secret Of Longevity?
2012-07-03 11:20:45

redOrbit Staff & Wire Reports - Your Universe Online The naked mole rat is well-known for its longer lifespan, living on average for 30 years. The East African native, when compared to humans, shows little sign of decline due to aging, maintaining high activity, bone health, reproductive capacity, and cognitive ability throughout its lifetime. Now a collaborative of researchers in Israel and the United States is working to uncover the secret to the small mammal's long and very busy...

Rats Have Best Bite Of Rodent World
2012-04-30 07:36:42

Scientists at the University of Liverpool have found that mice and rats have evolved to gnaw with their front teeth and chew with their back teeth more successfully than rodents that 'specialize' in one or other of these biting mechanisms. Researchers designed a computer model to simulate the bite of rats to understand whether their skull shape or muscle arrangement was a major factor in their evolutionary success and global dominance, making them one of the most common pest species in the...

Dr. Claudia Bieber from the Research Institute of Wildlife Ecology (FIWI) of the University of Veterinary Medicine, Vienna, and fellow scientists analysed a capture-recapture data set on common dormice (Muscardinus avellanarius) to investigate the life-history strategy of this species. These small rodents are about the size and weight of a wood mouse (Apodemus sylvaticus), but, unlike their rodent cousins, they hibernate — usually from late September/October to April/May. This is...

From miniature elephants to monster mice, and even Hobbit-sized humans, size changes in island animals are well-known to science. Biologists have long believed that large animals evolving on islands tend to get smaller, while small animals tend to get bigger, a generalization they call "the island rule." A new study by researchers at Duke University and the National Evolutionary Synthesis Center in Durham, NC puts that old idea to the test in island and mainland rodents. "Some of the...

Some of Ireland's oldest inhabitants are facing serious threat and possible extinction because of foreign species, according to researchers at Queen's University. The red squirrel, Irish hare and red deer are just some of Ireland's indigenous species which are under threat as a result of the introduction of foreign species. A new study which took place over the last two years looked at the impact of two introduced species — the bank vole and greater white toothed shrew — on two...

Rat Frees Trapped Cagemate In New Experiment
2011-12-09 07:59:05

While being referred to as a rat usually has negative connotations, a new study from the University of Chicago has revealed that rodents could be actuaally be generous and empathetic to their fellow creatures. According to a Thursday article by David Brown of the Washington Post, researchers at the university were attempting to find out whether or not one rat would release another from "an unpleasantly restrictive cage" if it had the opportunity. The answer, as it turns out, was yes. As...

African Pygmy Mouse, Mus minutoides
2012-05-15 07:41:59

The African pygmy mouse (Mus minutoides) can be found in the sub-Saharan areas of Africa. This mouse, perhaps the smallest of all rodents, can also be found living as pets around the world. Being social creatures, African pygmy mice will live in colonies preferably around water in grassy areas. When kept as pets, the mice cannot be left alone. Although the underbelly of the African pygmy mouse is a pale white, the rest of fur is colored reddish orange. The triangular ears, although small,...

The Patagonian Mara, Dolichotis patagonum, is a relatively large rodent found in Central and Southern Argentina. Maras inhabit arid grasslands and scrub desert. Maras like to live in burrows and will occasionally inhabit burrows that already exist from other animals. They are herbivorous. The Patagonian Mara is from the Family Caviidae, which includes cavies, such as their larger relative the capybara, and guinea pigs. Patagonian Maras are closely related to the other member of the...

The Little Swan Island Hutia, Geocapromys thoracatus, was native to Little Swan Island, off north-eastern Honduras in the Caribbean. The ancestors of the species may have been carried to the island from Jamaica, 5,000-7,000 years ago. It may have been a subspecies of the Jamaican hutia (Geocapromys browni). The Little Swan Island Hutia was a slow-moving, guinea pig-like rodent and probably emerged from caves and limestone crevices to forage on bark, small twigs and leaves. It was fairly...

The African Pouched Rat, Cricetomys emini, also known as Emin's Rat, is a large rodent in the muroid super family. It is related to the Gambian Pouched Rat. They are native to Africa and are found along the edges of forests and along the plains. Emin's rats are actually better climbers than their better known Gambian pouch rat cousins. These pouched rats are named for having cheek pouches much like a hamster. The African Pouched Rat has a distinct line of color difference between their...

Chinchillas and their relative's viscachas are small, twilight rodents native to the Andes Mountains in South America. They belong to the family Chinchillidae. Chinchilla fur is considered the softest in the world and is thirty times softer than human hair. Chinchillas must regularly bathe in dust or volcanic ash to remove oil and moisture that gathers in their thick fur. They have the highest fur density of any land animal with more than 20,000 hairs per square cm. Their fur is so dense...
